CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 317,178, dated May 5,1885.

v Application filed December 20, 1884. (No model.)

To all whom it may concern:

Be it known that I, HENRY A. NIEHAUs, of the city of St. Louis, State ofMissouri, have invented a certain new and useful Improvement inCar-Oouplings, of which thei'ollowingis a full, clear, and exactdescription, reference being had to the accompanying drawings, formingpart of this specication.

Figure lis a horizontal section at l l, Fig. 2. Fig. 2 is a verticallongitudinal section at 2 2, Fig. 1. Fig. 3 is a front endview of adrawhead. Fig. 4 is a transverse section at 4 4, Fig. 6. Fig. 5 is atransverse section at 5 5, Fig. 6. Fig. 6 is a side view.

A is part of the draw-head body, secured to the car in any usual orsuitable manner.

B is the recess to receive the end of the link O, which link may be ofordinary construction. It must, however, have sufficient length to allowthe working of the latch D upon its pin E when that end of thelink is inits inner position, as shown at m, Fig. 2.

The top andy bottom of the draw-head are slotted longitudinally at F andG, the latch working in these slots. Y

H is an elevation extending above the floor of the cavity or recess B,said elevation being inclined on the front and rear side, so that theend of the link will freely slide over the elevation in entering andleaving the draw-head and surround the elevation. The slot G may extendto the apex of this elevation, ,as shown, so as to avoid any tendency inthe link to bend the latch, as the elevation may extend above the levelof the point of bearing of the link upon the latch, so that the strainof the link upon the latch may be in direct line with the elevation. Bythe use of this elevation `the latch may be shortened, so as to lessenthe distance it is necessary the link should enter the draw-head toallow the latch to swing within it.

D is a horn on the rear side of the latch D, which holds down the innerend of the link,

l and thus sustains the link in a horizontal position, so that itwillenter the draw-head of another car. This horn may have a knob, D2, tocheckthe inward movement of the link when entering the draw-head ofanother ear.

I are ribs in the upper corners of the recess B, which prevent the innerendof the link flying upward when the cars are coupled and mounting theback of the horn D. tive construction of the elevation H and ribs issuch that the end of the link may pass between them with sufcient easein entering or leaving the recess B.

D3 is a handle upon the latch, by which the latch may be thrown up intothe position shown in Figs. l and 3 and in Fig.` 2 at to allow link tobe drawn out when uncoupling the cars. The coupling of the cars isautomatic, the end of the link forcing the latch upward and backward inentering the recess B.
